Application ined December 2, 191e.

To all whom 'it may concern Be it known that I, CLARENCE ARTHUR`Kxownnniin, a British subject, residing at have invented certain new anduseful lmprovements in lVire-Netting Machines; and

hereby declare that the following is a full, clear, and exactdescription of the saine,

My invention relates to a wire netting inachine comprising twisting anddrivingv elements so arranged that the mesh wires will be twisted aroundlongitudinally arranged strand wires, and one of the objects of myinvention is to so construct the machine that the strand wires will passaxially through the driving elements and be prevented thereby frombeing' entangled with the twisting mechanism.

A further object of my invention is to so construct the driving andtwisting elements that they will converge in the direction of the meshroller, this convergence creating a tapering formation of the drivingelements, which permits of the employment of conical shaped cop tubeswith increased cop holding capacity without a corresponding increase inthe width of the wire netting, the cop tubes extending through thetwisting mechanism to permit of the wire cops being readily placedtherein without the necessity of removing said cop tubes from themachine.

ln carrying out these objects I have made the driving elements of atapering shape, and have formed through each of the driving elements anaxial bore extending from one end to the other, and have mounted thesedriving elements in suitable bearings,

which are so constructed as to resist the end thrust of the drivingelements and their related parts, and I have provided the drivingelements with trunnions on which are slidably keyed clutch members toengage with the clutch members of the driving pinions loosely mountedupon the trunnions yand meshing with a rack by which motion istransmitted to the driving elements when the clutch elements areengaged, and I have so arranged these clutch elements that when the rackis moving in one direction it will transmit motion to alternate drivingelelments, and cause their rotation, and will on the return motion ofthe rack cause the rotation of the remaining driving elements.

l have. provided the twisting elements with conical-shaped cop tubeslocated in vthe intervals between each adjacent pair ofdriving'elements, and l have extended the bores of the cop tubes throughthe twisting elements so that the wire cops can be introduced into thecop tubes without necessitating their removal from the machine.

For an understanding of the invention reference is to be had to thefollowing description, and to the accompanying drawings in which Figurel is a plan view of thewire net-y ting machine. Fig. 2 is a frontelevation of the machine, y Fig. 3 is a rear elevation, Fig. is a brokensectional view showing the bearings for the driving and twisting`elements, Fig. 5 is av Vsectional view through the driving and twistingelements, on thel line if-a, Fig. 4e, Fig. 6 is an elevation of thebearings for the driving and twisting elements shown in Fig. 5, Fig. 7is a perspective view of one of thel driving elements,

Fig. 8 is a perspective view of one of the twisting elements, Fig. 9 isa detail view of the levers for moving theclutch members of the drivingelements, and Fig. 10 is a broken view of the wire netting.

Like characters of reference refer to like parts throughout thespecification and drawings.

On the top of the frame a near the front thereof is a slide way b forthe rack c, and meshing with the rack c kare a set of pinions d, cZ,'cZand d3. These pinions are loosely mounted upon the trunnions e of thedriving elements f, f', 7, and farespectively, the trunnions beingjournaled in bearings g in the gear box L. The gear boX h is fastenedlto the frame a above the slide way vY), and the trunnions projectthrough the bearings g to the front of vthe gear box.

The pinions d, ci are each provided,pref

erablv with a ratchet faced clutch member-A 'p z', and the pinions cZ,Z3 areeach provided preferably with a ratchet faced clutch member t',the inclined surfaces of the clutch vmembers e" being reversed withrespect to p the clutch members i of the pinions and c ments at the rearend of the machine, where the netting is formed, corresponds to thefidth of the netting, and that the width of the front end of thetwisting and driving elements is relatively greater than the rear end,to permit of tapering cop tubes being employed to contain conical shapedcops of wire for forming the meshes. By making these cop tubes of aconical shape it is possible to increase their wire holding capacitywithout increasing the width of the wire netting.

The tapering formation of the driving and twisting elements in additionto permitting of an increased holding capacity of thel cop tubes, alsohas the advantage of creating a relatively tight fit of the journals intheir bearings as the bearings are tapered to correspond with the taperof the journals, and owing to the action of the mesh roller in drawingthe wires through the cop tubes, a strain is imposed on these parts andon the driving elements rearward of the machine, which has the effect ofcausing the tapering journals to continually bear toward the smaller endof the bearings. To resist the end thrust of the driving and twistingelements the bearings a are provided with thrust shoulders a3 whichengage the adjacent side faces of the tapering journals and lunes andthus prevent them binding in their bearings, see Fig. 4.

The rack c is moved back and forth by meansof a lever c fulcrumed to theframe of the machine and actuated by a disk and pin c rotated by a shaftg revolved by bevel gear wheels g driven by the shaft g3.

The mesh roller w is driven from the shaft g3 by an eccentric motion t,and the winding roller e is driven from the mesh roller w by a belt andpulley drive fw".

rIhe above described motions for the rack, mesh roller, and windingroller may be varied within the scope of the appended claims withoutdeparting from the principle of the invention.

Having now fully described and ascertained the nature of my saidinvention, and in what manner the same is to be performed, I declarethat what I claim is 1. In a wire netting machine, a set of twistingelements, each comprising a tapering tube for a wire cop and lune-shapedmembers near the ends of said tube, in combination with a set of drivingelements each comprising two tapering journals, with lune-shapedrecesses in their peripheries to receive the lune-shaped members of thecop tubes, and a connecting member for said journals, said ournals andconnecting members being axially bored for the feed of the strand wires.

2. In a wire netting machine, a set of twisting elements, eachcomprising a tapering tube for a wire cop and lune-shaped members nearthe ends of said tube, in combination with a set of driving elementseach comprising two tapering journals, with. lune-shaped recesses intheir peripheries to receive the lune-shaped members for the cop tubes,and a connecting member for said journals, said journals and connectingmembers being axially bored for the feed of the strand wires, and meansvfor causing the.

strand wires, and means for causing the revolution of the alternatedriving elements and all the twisting elements, said means comprisingtrunnions projecting beyond the journals at one end of the drivingelements, pinions with clutch members loosely mounted on said trunnions,clutch members .slidably keyed on said trunnions and engaging those ofsaid pinions, and a rack meshing with said pinions to cause theirrevolution.

4.

5. In a wire netting machine, a set of twistingelements each comprisinga tapering tube for a wire cop and lune-shaped members near the ends ofsaid tube, in combination with a set of driving elements,

eaeli comprising tWo tapering journals, with lune-shaped recesses intheir peripheries to receive tlie lune-shaped members for the cop tubes,and a connecting; member for said journals, said journals and connectingmembers being' axially bored for the feed of the strand Wires, means forcausingthe revolution or' the alternate driving elements and all thetwisting elements, said means comprising trunnions projecting beyond thejournals :1t one end of the driving elements, pinions with clutchmembers loosely mounted on said trunnions, clutch members slidably keyedon said trunnions and engaging those or' said pinions, and a rackmeshing with said pinions to cause their revolution, the clutch membersof the alternate driving elements being oopositely disposed, where* byone half the number of driving elements Will be revolved as the rackmoves in one direction, and tbe other half will be revolved as the raelimoves in the opposite direction, and means actuated by the clutchmembers or' the alternate driving elements tor moving the elutelimembers of t ie remaining driving elements into engagement at eachreversal of tlie movement of said rack.
